I’ve expanded on Logical topics on the Thomistic Philosophy Page website beyond what I had about Substance and Accident in relation to Natural Philosophy. The new material includes a more complete (but by no mean comprehensive) treatment of the basics of Aristotelian-Thomistic Logic. Please see the Logic – Overview page for links to the following pages:
I. Logic and the Seven Liberal Arts
- Boethius and Early Medieval Logic
- The Art of Logic and the Science of Reason
II. Simple Apprehension – The Intellect’s First Act of Abstracting from Sense Experience
- Words, Concepts, Things
- Forming Definitions
- Porphyrian Tree
- The Problem of Universals
- Form or Species
- What the Meaning of “IS” is
- Predicaments – The Ten Categories: Substance and Nine Accidents
- First and Second Intentions
III. Judgment: The Intellect’s Second Act of Composing and Dividing
- Propositions and Judgments
- Truth and Falsity
- First Principles
- Types of Propositions
- Quality
- Quantity
- Square of Opposition
IV. Reasoning – The Intellect’s Third Act of Demonstrating
- Categorical Syllogism
- The Perfect Syllogism – the First Figure
- Hypothetical Syllogism
- Demonstration and Scientia
- Logical Relations Reflect Reality
This material also constitutes Chapter 2 of To Know the Truth of Things: An Overview of the Philosophy of Saint Thomas Aquinas, my forthcoming book. Look for it soon!
You will also find on the website hierarchal menus on the top of all the pages to allow navigation to some less obvious content on the site. Be sure to like and share with all and sundry. Gracias!
